Abstract: 1,142,194. Digital - analogue converters. SPERRY RAND CANADA Ltd. 15 June, 1966 [16 June, 1965], No. 25463/65. Heading G4H. The angle through which it is required to rotate a shaft 32 is stored in binary coded form in a register 6, the outputs from all but the two most significant stages of which control switches 7-10 to selectively connect resistances 2-5 in series with resistances 21 or 22 which are in parallel so that the sine and cosine of the stored angle are represented by the A.C. signals on leads 15 and 20 respectively. The signals are applied to the coils of a resolver 24, the two most significant bits in the register 6 being fed to a quadrant switching circuit 23 so that the outputs on the leads 15, 20 are applied to the appropriate coils of resolver 24. The alternating magnetic field produced by the energized windings induces a voltage in a rotor winding 29 of the resolver which is applied to a servomotor 31 to drive the rotor via the shaft 32 to an angular position in which the voltage induced in the rotor is zero, i.e. when the shaft 32 has rotated through an angle represented by binary coded input signal.

Filed: 1968-05-29
Abstract: 1,180,504. Rotary piston I. C. engines. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL. May 29, 1968 [June 7, 1967], No.25644/68. Heading F1F. In a rotary piston I. C. engine of the trochoidal n and n + 1 lobe type, at least one opening 14, Figs. 1 and 2, is formed in each of the end walls 12, 13 of the casing so as to facilitate the escape of a cooling and lubricating liquid from an annular space 11 between a pair of coaxial sealing rings 7, 8 lodged in each end of the piston, said liquid entering said space from the interior of the piston due to leakage across a surface 9, Fig. 4, of the ring 7. Each of the openings 14 resides within an area 16 wherein during operation of the engine it is never obturated by any part of the respective ring 7 and any part of any of a plurality of axial - sealing strips 4, 5 and is never overlapped by the ends of grooves for radial-sealing strips 3, each opening being periodically traversed by the respective ring 8 so that it lies first to one side of this ring and then to the other side, alternately. When each opening lies radially beyond the ring 8 gases leaking across the strips 4, 5 are relieved of pressure by them ejecting any liquid within the opening into a tank (not shown) through cavities 15 in the corresponding end wall of the casing, the tank being vented to facilitate the escape of said gases to the ambient atmosphere. The cavities 15 may be used to effect cooling of the end walls, in which case the opening, or openings, 14 in one end wall may be dispensed with, the spaces 11 adjacent the ends of the piston being connected to each other by at least one duct, (27, Fig. 6, not shown), within the piston. The tank aforesaid may be replaced by a separating chamber (20, Fig. 3, not shown), adjacent one of the end walls of the casing. The sealing rings 7, 8 are pressed against the adjacent end wall 12, or 13, by a flexible and resilient ring 26; and each pair of sealing rings may be rendered integral with each other, Fig. 5 (not shown).

Abstract: 1,089,062. Impedance matching. BELLING & LEE Ltd. June 18, 1965, No. 25785/65. Heading H1W. [Also in Division H4] An aerial support beam comprises two spaced apart members between which is a two-tube balun whose electrical characteristics are adjustable by altering the spacing between the tubes and by moving a shorting link along them. The beam projects from a tower, to which it is fixed, and an aerial is secured to its projecting part. As described, the beam comprises a metal channel having side walls 45, 46, Fig. 1, the balun tubes 39, 40 being contained therein by means of U shaped blocks (84), (85), (86), (87), Figs. 2 and 4 (not shown), and clamping bars (92), (93). Block (84) at the tower end is made of metal and the others, of insulating material. The insides of the blocks are made wide enough to allow adjustment of the distance between the tubes and two short pieces of channelled metal (102), (103) are interposed between the tubes and the block (84) to prevent any inadvertent rotation. An adjustable short-circuiting clip comprises two tube clamps 104, 105, Fig. 1, embracing the tubes 39, 40 and connected by a copper ring 108. A length of coaxial cable passes through one balun tube and at the tower end of the beam is terminated in a socket 52 which is mounted on a baffle-plate 50 secured in the channel member. A plate (76), Fig. 5 (not shown), for fixing the beam to the tower is welded to the channel member (44) and is strengthened by gusset plates (80), (81). A cover in two parts (57), (58) for the open top of the channel member (44) is held in place by nuts (69) with washers (70) engaging bolts (53), (54) secured to the floor (47). At the end of the beam remote from the tower a plate (48) with a rectangular aperture (49) is fitted to the channel member (44). On this is bolted an aerial junction box 5, Fig. 1, from which extends transversely an aerial dipole formed by two tubes, 1, 2. The dipole may be secured to the beam so that its axis is horizontal (Fig. 8, not shown) or vertical (Fig. 9, not shown). The junction box 5 contains a mass of electrical potting material 6 in which are embedded four lugs 7, 8, 9, 10 which are suitably connected to the dipole tubes 1, 2. Connections between the lugs 7, 9 or 8, 10 and the balun tubes 39, 40 are made by means of tubular connector links 24, 25 which have apertured flattened ends (Fig. 7, not shown). At the balun tubes they engage with screwthreaded shanks (37), (38) which project from the ends thereof (Fig. 6, not shown). The coaxial cable is also connected to an appropriate one of the lugs. Access to the lugs is obtained via an aperture 30, Fig. 1, in the junction-box 5, which is normally covered by a plate 33.

Title: Improvements in the treatment of textile materials
Inventor: MARSH JOHN THOMPSON
IPC: D06M15/423
Filed: 1950-10-24
Abstract: An aqueous bath for impregnating fabrics to give them improved tensile strength and crease resistance comprises a mixture of (1) a crystalloidal intermediate aminoplast condensate, e.g. as prepared in Specification 449,243 and (2) a colloidal aminoplast condensate as prepared in Specification 517,011 preferably with a hardening agent, e.g. ammonium dihydrogen phosphates.  Fillers, e.g. starch, delustring agents, e.g. BaSO4, and synthetic or natural rubber latices may also be added.  The bath is applied to the fibres and the condensates hardened in situ (see Group IV(c)). Melamine-formaldehyde or urea-formaldehyde condensates may be used as the aminoplasts.ALSO:Cellulosic textile materials e.g., flax, cotton or regenerated cellulose rayon are given an increased resistance to wet and dry creasing and to abrasion, and an increased stability and tensile strength, by impregnating them, locally if desired, with an aqueous solution of a crystalloidal intermediate condensation product of an amino-aldehyde resin and an aqueous solution of a colloidal intermediate condensation product of an amino-aldehyde resin, and then drying and heating the impregnated materials, e.g., to a temperature above 110 DEG C., in the presence of an acidic catalyst, to form the resins, the quantity of crystalloidal condensation product being greater than that of the colloidal condensation product and the total amount of resin formed upon the textile being at least 2 per cent by weight of the untreated material.  The textiles may be impregnated first with the crystalloidal condensation product, and if desired, dried and heated, and then with the colloidal condensation product and again dried and heated, or the condensation products may be applied together.  Specified condensation products are those of urea or melamine with formaldehyde, and the crystalloidal type may be prepared as described in Specification 449,243 and the colloidal type as described in Specification 517,011.  The heating operation may be effected in the presence of steam.  During or after drying, mechanical effects, e.g., crimping, pleating, calendering, Schreinering or embossing, may be imparted to the materials.  The solution of the colloidal condensation product may contain fillers, e.g., starch, and delustrants, e.g., barium sulphate or pigments and the solutions may also contain synthetic or natural rubber latices, water-proofing and spot-proofing agents.  Cotton and linen are preferably premercerized to increase their absorbency, and linen fabrics treated according to the invention may subsequently be treated with caustic soda as described in Specification 437,361.  The Provisional Specification specifies the following ingredients for addition to the impregnating solutions; dextrin, china clay, colloidal dispersions of silicon compounds, and water-repellents such as stearamino pyridinium chloride, octadecyloxymethylpyridium chloride and wax emulsions.

Title: Reversible gel composition and method of preparation
IPC: C08F20/62
Filed: 1945-10-04
Abstract: Thermal reversible gels are formed by dissolving, at slightly elevated temperatures in water made alkaline and having a pH of 4 to 9, interpolymers of acrylic or alpha-substituted acrylic acid with an acrylic or alpha-substituted acrylic amide and cooling the solution until it gels.  Gelatin in an amount less than that of the interpolymer may be added.  Specified acrylic compounds include acrylic and methacrylic acids, acrylamide, methacrylamide, alpha-phenyl acrylamide and alpha-chloroacrylamide.  Other vinyl compounds, e.g. acrylic acid esters or vinyl esters such as vinyl acetate, may be incorporated in the interpolymer.  Interpolymers containing vinyl esters may be hydrolysed.  Polymerization may be effected by heating at 20-100 DEG  C. in the presence of a catalyst, e.g. benzoyl peroxide, ammonium persulphate, sodium perborate, percarbonic and perphosphoric acids, hydrogen peroxide and ozonides. The polymers may be later modified by esterification with a polybasic acid or a polyhydric alcohol such as ethylene glycol or glycerol. Suitable alkaline compounds to impart the required pH include the alkali metal hydroxides and carbonates, ammonium hydroxide, methylamine, ethylamine, triethylamine and pyridine.  The gels may be used in photographic emulsions as protective colloids for sensitive materials, e.g. silver halides, as subbing layers, overcoatings or backings for films, as light filters, adhesives and thickening agents.  Specification 626,625 is referred to.

Patent GB-847669-A (GB)
Title: New starch products and processes for making same
Inventor: KERR RALPH W
IPC: C08B31/16
Filed: 1957-08-19
Abstract: A chemically modified starch sulphate is prepared by reacting, in an aqueous system at a pH above 7, starch, a tertiary amine-sulphur trioxide compound and a chemical starch modifying agent whereby the starch is simultaneously sulphated and chemically modified.  By the term "chemical modifying agent" is meant an enzyme, an oxidising agent, a derivatizing agent or a dextrinizing agent.  The derivatizing step includes etherification and esterification and a variety of mixed derivatives may be produced, cyanoethyl starch sulphate and mixed phosphate-sulphate of starch being novel compounds.  The process may be effected at room temperature or at any temperature up to the gelatinization temperature, or higher when salts are present to increase the gelatinization temperature.  It is desirable that p  the sulphation be limited to the range of 0,009 to 0,15 D.S. Trimethyl-amine- and triethylamine sulphur trioxides are the preferred sulphating agents but the sulphur trioxide compounds of other trialkyl amines and cyclic and heterocyclic tertiary amines may be used.  The products are useful as gelling, thickening and emulsifying agents in foods, as textile sizes, paper coating agents, protective films and drilling mud adjuncts.  In examples, (1) cyanoethyl starch sulphate is obtained from starch, acrylonitrile and trimethylamine-sulphur trioxide in water ; (3) Starch sulphate-phosphate ester is obtained from starch, sodium trimetaphosphate and trimethylamine-sulphur trioxide in water ; (2) a suspension of ungelatinized starch in gelatinized cyanoethyl starch sulphate is used to form protective films.ALSO:Fruit pie fillings are made by mixing the acid juice of canned sour cherries with a starch sulphate-phosphate mixed ester (see Group IV(a)) and sugar, heating the mixture to a boil and then adding the cherry meats.  The fillings are then poured into pie crusts and baked.
